Be it known that I, ARTHUR R. BROOM- HALL, a citizen of the United States, residing at Paris, in the county of Bourbon and State of Kentucky, have invented a newand useful Improvement in Heaters, of which the following is a specification.

This invention relates generally to heatingstoves, and more particularly to the means for supplying air to the fuel and also to the special construction of the fire-pot for receiving the said fuel and permitting the ready access of the air so fed to the fuel, one object of the invention being to provide an exceedingly cheap and simple construction of the fire-pot, by means of which a sufficient air-space is left for the circulation of air, and another object of the invention is to provide an air-feed pipe and duct for the purpose of introducing the air into the combustion-chamber, said feed devices being so arranged that the air will be heated as it passes the combustion-chamber.

With these various objects in view the invention consists in the peculiar construction of the vario-us parts and in their novel combination and arrangement, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming part of this speci- Iication, Figure 1 is a vertical sectional view of a stove constructed in accordance with my invention. Fig. 2 isa section taken on the line 2.2 of Fig l. Fig. 3is a detail view of one of the ribs of the fire-pot and also showing a portion of the ring upon which the rihs rest. Fig. 4 is a horizon tal section on the line 4 4 of Fig. l.

In the practical application of my invention I employ a vertical construction of a stove A, having a feed-door A and a smokeflue A2. An opening B is produced in the front of the stove above the feed-door, said opening having a door B hinged to the cover of same, said door being regulated by means of a ratchet-segment B2, so that said door can be partially opened to any extent desired.

An air-pipe C extends from the opening B to an air-duct D, arranged vertically in the rear portion of the stove, said duct being closed at its upper end, which is arranged di.- rectly beneath the smoke flue or pipe A2,whi1e Serial No. 708,139. (No model.)

l the lower end of said duct is opened and discharges into the ash-chamber E.

Any suitable construction of grate is arranged in connection with my stove, said grate resting upon the inwardly-extending radial arms F; These arms also support a circular ring G, upon which rest the lower ends of the sections H, forming the fire-pot. Each section is preferably constructed with the side ribs or ianges H and central rib H2, the upper ends of the side anges being tapered or beveled, as shown at H2, in order that the sections may be arranged at an inclination and have the flanges rest against the sides of the stove-body. The side Iianges H do not extend entirely to the bottom of the ribs; but the central rib H2 does extend entirely to the bottom and at its lower end is formed with a notch H4, adapted to receive the ring G, thereby forming a connection between the said ringl and the rib, and it will also be noted that the ring has a series of notches G in order to receive the central rib H2, thus preventing any possible motion of the said section H. The ribs are also provided with lata erally-projecting lugs H5 at the top and bottom of one side, the purpose of which is to properly space the ribs and hold them a suf= flcient distance apart to permit the free circulation of air around and through the tire-pot. As before stated, the upper ends of the ribs rest against the sideof the stove-body, and a conical liningring K is inserted in thestove and rests upon the upper ends of 'said sec'- tions, thereby securely covering them and holding them in their proper positions. If desired, the lugs H5 may be omitted and the vsections arranged close together; butin practice I prefer to arrange them as shown. The conical ring K does not extend entirely around the stove, as shown, inasmuch as the vertical duct D at the rear of the stove prevents the same, and it will also be noted that this vertical duct virtually forms a portion of the repot and is supported at its lower end upon the same ring G as the sections of the fire-pot. The fuel is fed through the door A in the usual manner, and the door B is regulated as desired to feed the air. The air passes down through the pipe C into the duct D, into the ash-pit, and from there through the firepot, and inasmuch as the pipe and air-duct ICO are arranged in line with the stove pipe or flue the air will of course be rapidly heated, and thereby increase the combustion of the fuel in the fire pot or chamber. By regulating the air-feed dool` the combustion of fuel can be increased or decreased, as desired.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a heating-stove, the combination With a casing, of a series of radially-extending arms positioned in said casing and projecting inwardly, of a grate engaged by the outer ends thereof, a fire-pot comprising a series of sections properly spaced and provided with rearwardly-exten ding side anges beveled at their upper end and resting against the inner side of the casing, a notched ring resting on the radial arms and means whereby the said sections and ring are engaged, substantially as described.

2. In a stove of the kind described, a Vertical air-dnct, arranged at the rear of the lirepot and below` the stovepipe-opening, said airduct discharging into the ash pitorchamber, and an air-feed pipe extending from the front of the stove across the top of the fire-pot into the upper end of the air-duct, said air-feed pipe liavinga regulating-door at its outer end, substantially as shown and described.

3. In a stove of the kind described, a firepot consisting of a series of sections having a central rib and rearwardly-extending side flanges, laterally-projecting lugs secured on said side flanges and a supporting-ring upon which the sections rest, substantially as described.

4. In a stove of the kind described, a iirepot, comprising a series of sections having rearwardly-extending side flanges, and a central longitudinal rib, the upper portion ot' each section being inclined and adapted to rest Hush against the side of the stove, lugs on said side anges for spacing them apart and an annular ring upon which the said sections rest, substantially1 as described.

5. In a stove of the kind described, the combination with the body, of the ring supported therein, the ribs arranged upon the said ring and forming the fire-pot and vertical air-duet forming the portion of said firepot, an air-pipe leading into the said air-duct, and the regulating-door and means for adjusting the same, substantially as and for the purpose described.
